They did not have the viedo card on-hand, so I just dropped by a shop on the way home and bought a video card with the same chipset and memory.

Video: ATI Radeon 4890 - 48901GB2

I tried the new ATI drivers and I kept getting this error message.

Could not load file or assembly 'MOM.Implementation, Version=2.0.3470.20910, Culture=neutral, PublicKey Token=90ba9c70f846762e' or one of its dependencies.
The module was expected to contain an assembly manifest.

I was hoping it would help me with the problem that started after adding the new ATI card, my system just shuts down for no reason.

I noticed that this error seems to pop up in my logs poretty much right before the system reboots.

The Multimedia Class Scheduler service entered the running state.

That may just be coincidental.

I also get these errors:

CRITICAL
2009-08-10 17:19:19 The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power
unexpectedly.

Did you reinstall windows after you upgraded the hardware? If you didn't, unfortunately windows isn't amazing at reconfiguring itself to match your new cpu and motherboard etc.
So I would recommend reinstalling or even repairing your windows installation.

Same question different person: Did you reinstall the OS, or did you attempt to just run the computer without reinstallation? If so, bad idea, the OS, just doesn't like you doing that. Reinstall, and everything should be OK. I know it is a pain, and hopefully you have backed up everything. Good Luck.

Fresh Clean install as if you just finished putting an entirely new case together would sum that up! The infamous "MOM implementation" error has a direct being on the MS NetFramework being trashed with the swapout. Plus your original hardware profile is useless now due to the major hardware changes seen.

Clean install time! Sorry! But the lengthy list of problems are a direct result of all that.

sorry for a daft suggestion as i am on different hw, but with my ati card, for some reason my card keeps getting its clock/ram speed in a twist, and then windows crashes when i open any apps or desktop that use transitions ie the opening of media centre etc

I try using catalyst to reset them but it often fails, but my MB tweeking utility allows me to tame them, then all is ok for ages.

Thank you ALL for the replies, wonderful thoughts--I was just resistant to reinstall without cause but I had everything backed up to a USB drive so the reinstall was not tough.

I went through the re-install, and it crashed updating drivers, CHKDSK did some repair, then I decided to reformat the drive to be clean.

I inserted my trusty XP disk and did my one hour reformat--Yes, I know I did not have to do that, but I'm funny that way.

Then I inserted the Windows RC 64-bit disk, Custom Install and removed the partition and recreated it. Kicked the install off. Got all the way through the install and patches. Plugged in my 1 tera-byte drive and the system locked up. I rebooted, with the USB drive plugged in and some drivers installed on login and I rebooted again as instructed. Now I am all patched again, all programs installed, with virus protection of course, and all my icons are back where I want them and my desktop image is setup.

The voltage messages have gone away, so the install did at least achieve that.

I have been stressing the system a bit and it seems to be running happy right now. I will leave enough things running for the next few hour to know for sure that the system is fine and after some sleep I will let you know...

Good news for sure! I could make an observation however on how long it takes to perform a full format with the XP like an hour or so there while I wipe a drive clean by removing partitions, creating new ones, and even seeing them formatted for the OS that will go on in under 5 minutes!

Instead of booting from a Windows disk I simply boot from a live GParted cd or even a usb key made up with that in mind. It can be a real time saver. At least you now know your hardwares are still good however and 7 is running good so far!
